yAt Athe present time this particular opera-jA tionl in *the preparationof leather isrper'- formed n'ianually, t'wlo men working'preferably .asa team, each with his own bench or hide or skin and passes the othei.li'ide or skin to histeamomate. The workman who :takes the skin ,orhide from the vat of glue,

or` other material, places the one retained by him, grain side.down,onvr a'boardpreferably of cardboard, and by means of aslicki'ngtoolevens outthe hide "or skin and removes excess glue orrothermaterialfrom the hide" or skin.

The slicking,operation'as now performed is relatively slow and .it isextremely diilicult' to get-two mento work. together as a'team and.continuouslyas any indisposition of `one of -the .members of the teamslows downthe The logical development 4in this-art is from manual laborto machine work, .and in my present inven-Y tion lhave devised a.machine for smoothing or ,slicking out a hideor skin on 'a Vboard, theslicking operation being performed mechanicallyand at a much greaterlspeed than isv possible by hand. workand, further,

Pivotally mounted on the shaft'20`inthe U-shaped member 16 isA alever 21,V this lever being forked atvone end and in theY forked end areinwardly ex- Y tending stub shafts 22. On the innerend of Yio the stubshaft 22 are rotatably mounted the rollers 23 Vwhich fit within` theannular groovev 19. The lever 21 extends inwardly of Athe machine andterminates in a handle 24 which'handle is adapted to engage with thecatch vor stop V25 secured to the U-shaped member 15 by screws 26. Whenthe handle Y portion 24 engages with the stop or catch 25, the rollers23, engaging with the sides of the annular groove 19, will'move thesleeve Y17 toy its uppermost position, as vi-ewed in Fig. 1. This lever21 is provided with devices whichv will be hereinafter described.

The lower end of the sleeve 17 has formed fersA 31 being, of course,equal to each other Over each pair ofrollers runs in diameter. anendless fiexible belt 32 of rubber, canvas, or any other suitablevmaterial. Y Secured to each endless belt32 at intervals along the lengththereof and parallel to each other are slicking tools 33 and the numberof tools 33 may be-any desired. By reference to Fig. 2 it kwill be notedthat the. manner in which theslicking ktools 33 are secured to theendless belts 32 is such that a minimum of wear is'placed on the endlessbelts 32 as such belts move over the rollers 31. Rotatably mounted insuitable bearings in the rectangular framework 29 centrally with respectthereto and parallel to thev shafts are stub shafts 34 and 35respectively. Se-

cured to the outer end of the shaft 34 is a gear 36 that meshes with anddrives a similar gear 37' secured to the adjacent end of theshaft 30immediately to the left thereof,

as viewed in Figs. 1, 2 and 3. Secured to the inner end of such shaft 34is a bevel gear (not shown) that meshes with and is driven by a bevelpinion 38. Secured to the outer end kof the shaft is a gear 39'thatmeshes with and drives a similar gear 40 secured to the adjacent end ofthe shaft 30 immediately to the right thereof, as viewed in the figures.Secured to the inner end lof Ythe shaft 35 is a bevel gear 41 thatmeshes with, and is driven by, the bevel pinionf'38. The bevel gear onthe inner end vof the shaft 34 and the bevel gear 41 on they/inner endof the shaft 35are equal in diameter and pitch, also the gears 36, 37,39 and 40 are equal in Vpitch and diameter and therefore 'it will beobvious'that the right and left hand shafts 30 immediately adjacent tothe shafts 34 and V35 and, therefore, the endless belts 32,

will be driven at the same speed. `The bevel pinion 38 issecured t0 'ashaft 42 that is rotatably mounted in the sleeve 17 above described. Theshaft '42 extends' upwardly beyond the limit of the U-'shaped member 16and has mounted on'its top end a bevel gear 43 that meshes with and isdriven by abevel pinion 44 secured to a shaft 45 rotatably mounted in abearing` member formed integral with, and at the upper end of, theU-sliaped member 16.r The'upper endof the shaft 42 is splined, Vas shownin Y Fig.V 1, and the connection between the shaft 42 and gear 43 issuch that the gear 43 rotates with the shaft 42, but is capable ofrelative longitudinal. movement thereon. vSecured to the shaft 45intermediate the ends thereof is a worm wheel 47 that meshesV Y withkand is driven by a worm 48 secured to the driving shaft of a rmotor 49,and such Ymotor being secured toa platformO formed integral with, andextending outward from,v

the U-shaped member 16. p

Formed in the end Vof the member 46 and on the U-shaped member 15 arebearings in which is mountedfor vertical rotative movement a shaft 51.Secured to the shaft 51 l wheel 52 that meshes with yand isdriven by theworm 48 above described asV being secured to the driving shaft of themotor 49. Secured to the shaft 51 intermediate its ends is a cam discV53 that has secured,

to one face thereof a cam 54. Formed on the lever 21 intermediate thevrends thereof is a member 55 in which is secured a shaft 56 and on thisshaft 56 is rotatably mounted a. roller 57'that is adapted to engagewiththe cam 54, this construction enabling they vertical movement of thesleeve 17 and atadjacent to the upper end thereof is a worm i tachedparts to take placeautomatically 'andl mechanically.
